R-449A Refrigerant Gas
Continuous Operation for 1,000 Cycles (Option: Without Defrosting) The Defrost-free operation option allows for continuous operation of 500 hours without interruption (if test conditions are set for 15-minute exposure).
Automatic Pre-heating/Cooling Setting for Energy Saving (Registered Patent) An algorithm for calculating the minimum operation time for pre-cooling and pre-heating by constantly measuring the amount of heat required for processes in Eco mode.
Minimizing Frost Load by Defrost-Free Operation (Option) Until now, testing was interrupted when defrosting was necessary. Thanks to a unique development that stops frost formation at low temperatures by preventing external air infiltration (frost-free operation, patent 3514735) There’s no need for defrosting during cyclic tests, thus reducing test time and energy consumption.
Integration with Evaluation System Can be integrated with ESPEC’s conductor resistance evaluation system (sold separately). The system can continuously measure the resistance of solder joints and conductive parts of connectors in thermal cycling environments at low/high temperatures.
Precise Temperature Recovery Dampers with an integrated correction function minimize condition changes following sample insertion into the test area.
Sample Temperature Control Sample temperature display with trigger function (optional). Two temperature sensors are connected to the sample in the test area to measure sample temperature. This option includes a trigger function that switches to exposure testing after both temperatures reach the desired temperature, thus performing the most accurate thermal tests. *Cannot be combined with Eco Mode operation.
